"Hot-dip galvanizing" and "pre-galvanizing" are both galvanizing treatment methods for metal surface corrosion protection, but their processes and applications are different: 1. Hot-dip galvanizing:Process: The steel is immersed in molten zinc liquid (usually at a temperature of about 450°C) to reac

Hot dipped galv.seamless steel pipe is a steel pipe coated with a layer of zinc on the surface. The molten metal reacts with the substrate to form an alloy layer, so that the coating and the substrate are firmly bonded, and the thickness of the coating is uniform. It also has good corrosion resistance due to its galvanized coating.

The hot-dipped galvanizing refers to the metal surface treatment. The metal product will be immersed it in the bath of the molten zinc. The whole process of the hot-dipped galvanizing process can be divided into 3 parts, like the surface preparation, galvanizing, and inspection.

When people purchase steel pipe for pipeline systems, we always see the pipe required to be a epoxy coating like 3PE (3LPE) or FBE.

Hot dip galvanized tubes are steel pipes obtained by hot-dip galvanizing on the surface of the steel pipe. Hot dip galvanizing is the process of coating iron, steel or ferrous metal with a layer of zinc.
